FELIWAY Classic 30 Day Cat Calming Odourless Refill for Pheromone Diffuser, 48ml - Helps Solve Common Signs of Stress in Cats

Overview

Feliway Classic 30 Day Cat Calming Odourless Refill sits on our cat essentials shelf, where the ranking comes from what buyers actually said rather than from what the box says. From the seller's own listing: The FELIWAY Classic refill pack contains 1 x 48ml refill, compatible with a FELIWAY Classic diffuser. FELIWAY Classic helps cats feel calm, and reduces signs of stress such as scratching, urine spraying, scratching, fears, tension, and conflict. That is the maker talking, not us, so read it as a claim rather than a finding. Buyers have it at 4.6 out of 5 from 21,545 ratings. We work out below what that is worth against everything else on the shelf.

How it compares on the cat essentials shelf

The typical cat essentials product on our shelf scores 4.6 out of 5, measured across 49 rated products. This one comes in at 4.6. Mid-table, in other words. The stars aren't going to pick a winner here, so it comes down to pack size, cost per unit and the details further down.

That score rests on 21,545 ratings. The median for this shelf is 6,150. A score built on that many opinions is hard to shift and hard to game, which is why we weight review volume rather than ranking on stars alone.

On money, this sits in the top third of a shelf running from £1.19 to £29.99, with the midpoint around £12.69. It costs more than most while rating around the middle, so the extra money needs to be buying something specific: pack size, brand you trust, or a detail below that matters to you.
